I was showing a trainee how to save a file, with all the vehicle details being completed and managed to lose the waveform, while the save dialogue was still open!! I had a drop down open (I think it was selecting Channel B's item - ie "Battery voltage") and possible pressed a keyboard combo - [end] or [ctr+end], really not sure ... but a file loaded in the background and replaced my waveform! It loaded a file from the same directory that my starting template file had been loaded from, but it was not a recent file.
I finished the full save, just in case my data was still there, in the background somewhere, but it was not!
This is clearly a bug, you should not be able to load a new file while saving! (cable and scope where not unplugged, but this has happened during saving, another really annoying issue).
Also, the [enter] key takes you to the filename dialogue, with no way back to the vehicle page, please can you change the [enter] key to select the data - if in a drop down - and provide a path back to vehicle page, from the save filename dialogue. People love [enter] and use it to select, maybe use [ctr+enter] to move to the filename screen?
